Since the atmosphere and oceans formed, the volume of water on our planet has remained relatively constant.
That finite amount of water is what sustains all of us, and over the next 100 years both drought and flooding conditions are predicted to worsen across around the world, with water scarcity becoming a global issue.
As an individual, what kind of impact can any of us make?
It actually takes less than you would think...
That's enough to fill the entire Grand Canyon to the rim over 332 times.
The majority of freshwater is frozen or underground.
Can you make it?
